Compute Module 4S Based on the Raspberry Pi 4 Model B architecture, the Compute Module 4S is intended for industrial customers migrating from Compute Module 3 or Compute Module 3+. For new customers designing products, the use of the Raspberry Pi Compute Module 4 is recommended. The Raspberry Pi Compute Module 4 SODIMM (CM4S) is a System on Module (SoM) that contains processor, memory, eMMC flash and supporting power supply circuitry. These modules allow developers to use the hardware and software of the Raspberry Pi in their own systems and form factors. The SODIMM form factor compute modules have 18 additional GPIO pins compared to the standard Raspberry Pi boards, for a total of 46, giving designers more options.
